SLIDIN G DOOR.

structure where sliding doors are used.

The object of the invention is to provide improved means whereby a pairof sliding doors may be brought flush witheach other when closed, and inwhich one will pass behind the other when opened.

The apparatus includes improved means for causing lateral movement ofthe respeotive ldoors to enable one to pass behind the other, or tocause them to close in aline-v ment with each other.

The invention is illustrated in the accompanying drawings, in which`Figure 1 is a vertical section of a case having sliding doors providedwith the invention, the doors being open; Fig. 2- is a horizontalsection with the doors closed; and

Fig. 3 is a horizontal section with the doorsl open.

Referring specifically to the drawings, (i

indicates the base of the case and 7 the top- -oi metal plates having alength equal to the width of the doorway, and the lower guides arepivoted at their lower edges to swing laterally, by staples 15, and theupper guides are hung to swing laterally by staples 16, the former beingdriveninto a cross piece 17 in the base of the case and the latter beingdriven into the top piece of the case. The respective guides at top andbottom are located one behind the other, and will swing toward or fromeach other, after the manner of leaves. The front door is mounted on itsguides by means of grooved supports 1S and 19 which are set in the backedge of the door, and the rear door is mounted upon its guides bySpecification of Letters Patent.

means of similar grooved supports 20 and 21 which are secured to theback of said door, whereby the supports of the front door are slightlyoffset or out of alinement with the supports of the rear door, when thedoors are closed, as'indicated in dotted linesl ein Fig. 1, the purposebeingl to bring the outer surfaces ot the doors flush with each otherwhen they arel closed, as shown in dotted lines in Fig. 1 and in fulllines in Fig. 2. The respective guides at the top and bottom areconnected by rods 22 and 23 with opposite ends of levers 24 fast on avertical rod 25 which, for the purpose ot concealing the same, may beset in a partition at the middle of the case. Or, if no partition isused, the rod is left exposed.

'T he lower end of the rod is set in a bearing in a block 27 in the baseof the case and the upper end is set in a bearing in the top T.

In consequence ot the lateral movement or swing of the guides on whichthe doors slide, lsaid doors may be swung to pass each other. Assumingthat the case is closed, to open the same the door 10 is pressed in,which causes it to recede, its supports 13 and 14 swinging backwardly,and this movement swings the supports 11 and 12, and consequently thedoor 9, forwardly. r1`he doors being thus brought out of alinement,either or both can he Islid sidewise,'as usual, to open the same. lVhen.they are again closed, the. door t) is pushed back` or in, bringing thedoor 10 forward and flush therewith. The guides are so placed that thecenter of gravity of the doors falls beyond center when either open orclosed, thereby causing the doors to set in the desired position.Obviously rollers or other anti-friction devices may be used in- Isteadof the grooved supports Yat the top and bottom of the doors. The leversand connecting rods are preferably concealed in the top and bottomcompartments of the case, as shown in Fig. 1.

Various modifications may be made within the lscope of the invent-ion,especially with respect. to the particular construction of supportingguides` and no limitation 1s 1mplied by reason of the exact structureshown and described.

I claim: 1. The combination of a pair of sliding doors shiftablerespectively in and out to bring said doors in or out of alinement witheach other', and means connecting the doors 'to cause opposite relativeshift thereof.

. out of alinement with each other, and con- 2. The combination of apair of sliding l doors, uides upon which said doors are mounted, saidguides being movable laterally with respect to the line of trevelfof thedoors, to bring the doors in or out of elinement with each other, andconnections between the guides, constructed to cause opposite movementthereof.

3. The combination of a pair of sliding doors, guides upon which saiddoors 'are mounted, said guides being pivotally mounted to swinglaterally with respect tothe line of travel of the doors, to bring themin or nections between the uides, constructed to cause opposite swingtiereof respectively.

4f.y The combination of a pair of sliding doors,-guides ut top andbottom thereof, between Whioh the doors are mounted, the guides rbeingmovable laterally with respect to .the line of-travel of the doors tobring the sume in or out of alineinent with each other, and connectionsbetween the guides at top und bottom, constructed to cause similarmovement thereof.

5. The combination of a pair of sliding doors, guides for euch door attop und bottom thereof, onhwhich the doors are .supported and slidable,said Guides being pivotally mounted to swing aterally with respect tothe line of travel of the doors, to bring the doors in or out'ofalinement with each other, and connections between the guides to causeuniformi movement thereof, comprising an upright shaft behind the doors,provided with levers, and rods connecting the guides and the oppositeends of the levers.

In testimony whereof I aiix my signature in presence of two witnesses.
